IN74HC240A
OCTAL 3-STATE INVERTING BUFFER/LINE
DRIVER/LINE RECEIVER
High-Performance Silicon-Gate CMOS
The IN74HC240A is identical in pinout to the LS/ALS240. The
device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL outputs.
This octal inverting buffer/line driver/line receiver is designed
to be used with 3-state memory address drivers, clock drivers,
and other bus-oriented systems. The device has inverting
outputs and two active-low output enables.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
